You do realise Simon that using a torque wench with a crows foot is not accurate as you have a change in leverage !

As (CLF) Alan says sufficient tightness will easily be achieved with a good nip with a spanner particularly if coated with copper grease.
60 Nm is approximately 45 lb/ft and I can guarantee in everyday circumstances with a normal length 17 mm spanner and a straight pull everybody would easily exceed 60 nm
